Life in the future 一、閱讀理解 閱讀下面短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。 Plastic-Eating Worms Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋場), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms. Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a mercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms’ chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊狀物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass — apparently broken down by enzymes (酶) from the worms’ stomachs. Their findings were published in Current Biology in 2017. Federica Bertocchini, co-author of the study, says the worms’ ability to break down their everyday food — beeswax — also allows them to break down plastic. ＂Wax is a plex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, ＂she explains, ＂The wax worm evolved a method or system to break this bond. ＂ Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But pared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(腸道微生物)? Bertocchini agrees and hopes her team’s findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process — not simply ＂millions of worms thrown on top of the plastic. ＂ 1. What can we learn about the worms in the study? A. They take plastics as their everyday food. B. They are newly evolved creatures. C. They can consume plastics. D. They wind up in landfills. 2. According to Jennifer DeBruyn, the next step of the study is to . A. identify other means of the breakdown B. find out the source of the enzyme C. confirm the research findings D. increase the breakdown speed 3. It can be inferred from the last paragraph that the chemical might . A. help to raise worms B. help make plastic bags C. be used to clean the oceans D. be produced in factories in future 4. What is the main purpose of the passage? A. To explain a study method on worms. B. To introduce the diet of a special worm. C. To present a way to break down plastics. D. To propose new means to keep eco-balance. 【文章大意】本文為說明文。文章介紹了一種吃塑料的蟲子大蠟螟，它胃中的酶能夠降解塑料，這為解決塑料污染提供了新的途徑。 1.C 【解析】細節(jié)理解題。根據(jù)文章第三段Federica Bertocchini, co-author of the study, says the worms’ ability to break down their everyday food — beeswax — also allows them to break down plastic. 可知，研究結(jié)果發(fā)現(xiàn)，蠕蟲分解日常食物的能力讓它們可以分解塑料，也就是說它們可以消費塑料。故選C。 3.D 【解析】推理判斷題。根據(jù)文章最后一段But she expects using the chemical in some kind of industrial process — not simply ＂millions of worms thrown on top of the plastic. ＂可以推斷出，Bertocchini希望這種化學(xué)物質(zhì)將來能在工業(yè)生產(chǎn)中使用，而不是僅僅依靠蠕蟲來分解塑料。故選D。 4.C 【解析】寫作意圖題。根據(jù)文章第一段最后一句So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms. 可知，有一種新的方法被用于分解塑料。再根據(jù)最后一段最后一句But she expects using the chemical in some kind of industrial process — not simply ＂millions of worms thrown on top of the plastic. ＂可知，Bertocchini希望將這種方法推廣到工業(yè)中。由此可以推知寫作意圖為介紹一種分解塑料的方法。故選C。 二、教材與語法填空 根據(jù)教材課文內(nèi)容，在空白處填入1個適當(dāng)?shù)膯卧~或括號內(nèi)單詞的正確形式。 I went into the future because I 1.

There the trees acted as walls and provided oxygen 10. the room; a table, some chairs and a bed rose from under the floor as if by magic. 答案：1.had won　2.a　3.which/that　4.less　5.His 6．called　7.safely　8.different　9.belonging　10.for 三、完形填空 閱讀下面短文，從短文后各題所給的A、B、C和D四個選項中，選出可能填入空白處的最佳選項。 A Letter to My Dad Four years ago we found out about the cancer growing inside you.You told me the news that it had already spread and that you didnt know how long you had __1__.
